Subject: [PATCH 5/8] mac80211: remove unnecessary key condition
Date: Fri, 30 Aug 2019 14:24:48 +0300	[thread overview]
Message-ID: <20190830112451.21655-6-luca@coelho.fi> (raw)
In-Reply-To: <20190830112451.21655-1-luca@coelho.fi>

From: Johannes Berg <johannes.berg@intel.com>

When we reach this point, the key cannot be NULL. Remove the condition
that suggests otherwise.
